24 Va. Admin. Code § 30-91-110
A. General requirements. Most criteria addressing the design of new subdivision streets can be found in the Subdivision Street Design Guide (24VAC30-91-160). However, the following provisions are provided for guidance, particularly in regard to features that require agreements or formal acknowledgements of the governing body before VDOT's acceptance of the street or streets within a subdivision.
When an agreement is required between the local governing body and the department as a prerequisite to the acceptance of a subdivision street, nothing in these requirements shall preclude the local governing body from entering into separate agreements with other entities to fulfill its responsibilities. However, if the provisions are intended to ensure the safety of the public using the street, the department reserves the right to approve the involvement of the other party or parties.
D. Pavement structure.
E. Parking.
1. Perpendicular and angle parking along subdivision streets is normally prohibited. However, perpendicular and angle parking along subdivision streets may be considered if the features along the street cause the street to readily appear to be a street rather than a travel way through a parking lot. In addition, additional pavement width may be necessary between the travel lanes and the parking spaces to allow a car to back from its normal parked position, orient itself for entering the travel lanes and stop without either encroaching into the travel lanes or having the driver's vision of oncoming traffic obscured by adjacent, parked vehicles.
Street designs that anticipate the restriction of on-street parking shall only be approved with the consent of the county official and the resident engineer.
2. Localities are encouraged to adopt local ordinances to appropriately address adequate off street parking in subdivisions. In the absence of local regulations that are deemed acceptable by the department, the following criteria shall apply for the design of subdivision streets:
F. Cul-de-sacs and turnarounds. An adequate turnaround facility shall be provided at the end of each cul-de-sac or stub street to permit the safe and convenient maneuvering by service vehicles. Various configurations of turnarounds are illustrated in the Subdivision Street Design Guide (24VAC30-91-160); however, alternative configurations may be approved by the resident engineer. Additional right-of-way shall be provided as required by the design of the turnaround. Normally, any nontraveled way areas within the turnaround, such as an island, shall be included in the dedicated right-of-way of the facility.
For circular turnarounds, a well-defined, identifiable street segment, equal to the normal lot width along the intersected street that serves the cul-de-sac or 50 feet, whichever is greater, shall extend from the intersected street to the turning area.
G. Curb and gutter. For the purpose of these requirements, the use of curb and gutter is an acceptable roadway design alternative, rather than a requisite. However, when used, curb and gutter shall be designed in accordance with the Subdivision Street Design Guide (24VAC30-91-160) and only one curb and gutter design may be used along the length of a street.
I. Pedestrian, bicycle, and shared use path facilities. The Commonwealth Transportation Board's "Policy for Integrating Bicycle and Pedestrian Accommodations" emphasizes accommodating pedestrian and bicycle traffic as an essential part of any VDOT financed transportation project. While separate pedestrian and bicycle facilities are not mandated for local subdivision streets, unless required by local ordinance, any street proposed for VDOT acceptance should accommodate the anticipated pedestrian and bicycle traffic. When separate pedestrian and bicycle facilities are deemed appropriate, they should be included in the initial construction of the street, prior to VDOT acceptance. These facilities are eligible for VDOT acceptance based on the criteria of this section.
1. Compliant facilities. Pedestrian and bicycle facilities, including shared use paths as defined under § 46.2-100 of the Code of Virginia, shall be accepted as part of subdivision streets, unless otherwise requested by the governing body, provided they are located fully within the dedicated right-of-way of the street and they are constructed in accordance with applicable criteria and standards of the department.
2. Noncompliant sidewalk, bicycle, and shared use paths. Noncompliant sidewalk, bicycle and shared use paths that fail to meet requirements of the department's standards for construction, alignment, or placement within the dedicated right of the street shall be deemed to be noncompliant and not qualify for maintenance. However, such facilities may co-exist within the dedicated right-of-way of the street under a land use permit issued by the resident engineer to the local governing body responsible for having established the facility through its subdivision process.
Such permits will clearly specify the responsibility for maintenance of the facility and related activities to the extent the facility occupies the street's right-of-way. The permit applicant should be a county, incorporated town, or other entity that has perpetual maintenance capability. Noncompliant sidewalks and shared use paths may be constructed of bituminous concrete, hydraulic concrete, gravel, or other stabilizer convenient to the applicant.
J. Bridge, drainage, and other grade separation structures. Bridges, drainage, and other grade separation structures shall be designed and constructed in accordance with all applicable department criteria and standards. The resident engineer may require special review of the plans and construction inspection.
3. The projected traffic volume of the street is not less than 4000 vpd or, if the structure otherwise serves as part of the principle pedestrian access to a school and a peak hour traffic volume of 450 vph is projected.
In all other instances, the grade separation structure shall be deemed to be a county controlled grade separation structure within the right-of-way of the street, in which case the street will only be accepted as part of the secondary system of state highways maintained by the department after the local governing body and the department have executed an agreement acceptable to the department that (i) acknowledges the department has no responsibility or liability due to the presence of the structure and (ii) assures the costs of inspection, maintenance, and future improvements to the structure are provided from sources other than those administered by the department.
In all cases, whether the structure is accepted as an integral part of the roadway for maintenance by the department or it remains a county controlled structure, the responsibility for lighting, safety, and security of those using such facilities shall remain a responsibility of local government.
The department will accept grade separation structures as part of new subdivision streets provided the structure is a drainage structure or is intended to separate the movement of registered motor vehicles. In addition, the department will accept grade separation structures intended to separate pedestrians or bicyclists or any combination thereof from traffic using the roadway, provided:
K. Dams. The department will only consider accepting subdivision streets for maintenance that occupy dams when all of the following provisions are satisfied. For the purpose of this section, a roadway will be considered to occupy a dam if any part of the fill for the roadway and the fill for the dam overlap or if the area between the two embankments is filled in so that the downstream face of the dam is obscured or if a closed drainage facility from a dam extends under a roadway fill.
2. Design review. An engineer, licensed to practice in the Commonwealth of Virginia, shall certify that the hydraulic and structural design of any dam, as described below, is in accordance with current national and state engineering practice and that all pertinent provisions of the Subdivision Street Design Guide (24VAC30-91-160) have been considered. Prior to approval of the roadway construction plans, the hydraulic and structural design of a proposed dam shall be reviewed by and meet the department's satisfaction if:
6. Dams exempt from agreements. The acceptance of roadways that occupy dams shall be exempt from the requirements for an agreement with the governing body, as required by subdivision 1 of this subsection, if all of the following is satisfied:
L. Roadway drainage.
2. Stormwater management. Whereas the department considers matters regarding stormwater management associated with the construction of new subdivision streets to be under the authority of the local governing body, decisions regarding stormwater management in the construction of subdivision streets are deferred to the locality. However, stormwater management, including the construction of detention or retention facilities, or both, is recognized as an available design alternative. Where the developer is required by regulations promulgated by an agency or governmental subdivision other than the department or the developer chooses to use stormwater management facilities in the design of a subdivision, the governing body shall, by formal agreement, and as a prerequisite for the transfer of jurisdiction over the street to the department, acknowledge that the department is not responsible for the operation, maintenance, or liability of the stormwater management facility or facilities associated with the subdivision. However, in the event the governing body has executed a comprehensive, countywide agreement with the department addressing these matters, a specific agreement addressing stormwater management controls in the subdivision will not be required as a condition for street acceptance.
Stormwater management controls for VDOT projects are designed in accordance with the VDOT Erosion and Sediment Control and Stormwater Management Program Specifications Manual (24VAC30-91-160), the Erosion and Sediment Control Regulations, 9VAC25-840, and the Virginia Stormwater Management Program (VSMP) Regulation, 9VAC25-870. While these controls may be necessary whenever a street maintained by VDOT is widened or relocated, the department does not require them in the development of new subdivision streets, because such activity is regulated by the local governments. However, developers and counties may find these controls useful in managing land development activity.
Devices and treatments intended to mitigate the impact of stormwater shall be placed off of the right-of-way and shall be designed to prevent the backup of water against the roadbed.
Where development activity results in increased runoff to the extent that adjustment of an outfall facility is required, such adjustment shall be at the developer's expense and be contained within an appropriate easement.
3. Drainage easements.
M. Other design considerations.
4. Railroad crossings.
5. Utilities. Local governments, the development community, and the utility community are encouraged to coordinate and consolidate their interests as part of the initial development plan.
a. Underground utilities. The department allows the placement of underground utilities within the dedicated right-of-way of streets, but normally restricts placement to areas outside of the travel lanes and desirably beyond pavement areas. However, if the governing body has established adequate requirements for the design, location, and construction of underground utilities within the right-of-way of subdivision streets, including provisions that ensure that adequate testing and inspection is performed to minimize future settlement, those requirements shall become the department's requirements and govern unless those requirements conflict with a requirement of the department.
(2) May be acceptable beneath the travel lanes of the street when provisions are made to ensure adequate inspection and compaction tests and:
(b) Longitudinal installations and manholes are placed in the center of an undivided roadway out of the wheel path.
However, manholes shall not be placed in sidewalk or shared use path facilities within five feet of curb ramps or within driveway entrances.
When location of the utilities outside of the pavement area is not practical and is endorsed by the local government through its requirements, such installations:
b. Open-cutting of hard-surfaced roadways. The department usually prohibits the open-cutting of hard-surfaced roads except in extenuating circumstances. Therefore, all underground utilities within the right-of-way, as determined necessary by good engineering practice to serve the complete development of adjacent properties, shall be installed during the street's initial construction and prior to the application of its final pavement surface course. This shall include extensions of all necessary cross-street connections or service lines to an appropriate location beyond the pavement and preferably the right-of-way line.
In the event it is necessary to open the street pavement to work on utilities after the surface has been placed, additional compaction tests and paving as necessary to restore the integrity and appearance of the roadway may be required at the discretion of the resident engineer.
d. Aboveground utilities. All aboveground utilities shall be installed behind the sidewalk or as close as possible to the limits of the street's right-of-way but shall not encroach on the sidewalk, the shared use path, or any clear zone.
To assure the unencumbered dedication of the right-of-way for subdivision street additions, easements or other interests within the platted right-of-way shall be quitclaimed of any prior rights therein. In exchange, a permit may be issued by the department for a utility to occupy the area involved. This permit will be processed by the resident engineer upon acceptance of the street into the secondary system of state highways maintained by the department. No inspection fee is required for permits so issued. However, the approval of the permit shall be contingent upon the utility's compliance with applicable provisions of the Land Use Permit Regulations.
